Ah.. I may need a newer version of OTP?

I have OTP 21..
Erlang/OTP 21 [erts-10.2.1] [source] [64-bit] [smp:6:6] [ds:6:6:10] [async-threads:1] [hipe]

Tho.. this page mentions OTP 21+ https://erlang-ls.github.io/getting-started/vscode/

And on OTP 27.1 but running on a Mac (not dev container). But the extension installs 0.43 so I need to check with the current version.
